      If you have any concerns regarding site access please call our friendly customer services team on 0800 84 12 12 to organise a free site inspection before proceeding with the installation


    • The Gas (Safety & Measurement) Regulations 2010 affect the way in which OnGas delivers to customers and the way gasfitters install the appliances and cylinders at the customer site. Download a copy of this Regulation here

      In short, what this means for you:

      • The only person who can connect a new gas installation to a gas supply is the gasfitter.
      • OnGas cylinders left at customers installation cannot be connected by an OnGas delivery driver. Have the cylinders delivered to the site before you arrive at the site to do the installation/connection, or you’ll have to return to the site again to do it.
      • Any installation that has been disconnected for more than 6 months will have to be re-certified.
